Twenty Jewish children used in medical experiments at Neuengamme are killed in the basement of the Bullenhuser Damm school.

Nazi human experimentation was a series of medical experiments on prisoners by Nazi Germany in its concentration camps mainly between 1942 and 1945. There were 15,754 documented victims, of various nationalities and ages, although the true number is believed to be more. About a quarter of documented victims were killed and survivors generally experienced severe permanent injuries.

Neuengamme was a network of Nazi concentration camps in northern Germany that consisted of the main camp, Neuengamme, and more than 85 satellite camps. Established in 1938 near the village of Neuengamme in the Bergedorf district of Hamburg, the Neuengamme camp became the largest concentration camp in Northwest Germany. Over 100,000 prisoners came through Neuengamme and its subcamps, 24 of which were for women. The verified death toll is 42,900: 14,000 in the main camp, 12,800 in the subcamps, and 16,100 in the death marches and bombings during the final weeks of World War II. Following Germany's defeat in 1945, the British Army used the site as an internment camp for SS and other Nazi officials. In 1948, the British transferred the land to the Free Hanseatic City of Hamburg, which summarily demolished the camp's wooden barracks and built in its stead a prison cell block, converting the former concentration camp site into two state prisons operated by the Hamburg authorities from 1950 to 2004. Following protests by various groups of survivors and allies, the site now serves as a memorial. It is situated 15 km southeast of the centre of Hamburg.

The Bullenhuser Damm School is located at 92–94 Bullenhuser Damm in the Rothenburgsort section of Hamburg, Germany – the site of the Bullenhuser Damm Massacre, the murder of 20 children and their adult caretakers at the very end of World War II's Holocaust – to hide evidence they were used as human subjects in brutal medical experimentation.
